Why are we still suffering?

That the human brain is squishy

I spend the majority of my time quietly in a room alone, and I'm still suffering.

Many things about human brains are different than other primates. Our ability for language being most prominent. Many things are not different, however. Alpha seeking and advantage seeking behavior lead to tribalist behaviors seen in many primate communities where alphas fight to the death for leadership privileges and take mates from non-alpha apes. This leads to social structures that give rise to inequality in the group. Just like human society. We suffer because we refuse to all treat each other with dignity, trust and respect. We suffer because we don't let the reasoning and linguistic capabilities of our human brains dominate the animalistic drive of greed. Though it looks like we could fix this overnight ("we have the technology"), much like using tariffs to increase domestic production after globalism, that process can only be won in small steps. The best we can do is to teach our children to treat others as equals and to work together to punish those who victimize for personal gain. Eventually this could lead to a world where inequality fades away, but it will take millennia and who knows what will be left to share by then.

One reason is the attempt of advertisers to psychologically manipulate you into wanting things you don't really need, https://news.ycombinator.com/item?id=43595269.
